Further, in the same repeating unit group PXZ, theorthographic projection of the reset line RST on the base substrate 10does not overlap with the orthographic projection of the anode in thered sub pixel controlled by the reset line RST on the base substrate 10,the overlapped region is formed between the orthographic projection ofthe light-emitting control line EM on the base substrate 10 and theorthographic projection of the anode in the green sub pixel controlledby the light-emitting control line EM on the base substrate 10, and theorthographic projection of the scanning line GA on the base substrate 10does not overlap with the orthographic projection of all the anodescontrolled by the scanning line GA on the base substrate 10. Further, asfor the same repeating unit, overlapped regions are formed between theorthographic projection of the light-emitting control line EM forcontrolling the repeating unit on the base substrate 10 and theorthographic projection of the anode in the blue sub pixel on the basesubstrate 10 as well as between the orthographic projection of thelight-emitting control line EM for controlling the repeating unit on thebase substrate 10 and the orthographic projection of the anode in thegreen sub pixel on the base substrate 10 respectively, and theorthographic projections of both the reset line RST and the scanningline GA for controlling the repeating unit on the base substrate 10 donot overlap with the orthographic projection of all the anodes on thebase substrate 10. It should be noted that the reset line RST is asignal line for controlling the initializing transistor T6 and the resettransistor T7 in one repeating unit. The light-emitting control line EMis a signal line for controlling the light-emitting control transistorT4 and the conducting control transistor T5 in one repeating unit. Thescanning line GA is a signal line for controlling the data write-intransistor T2 and the threshold compensation transistor T3 in onerepeating unit.

The light-emitting control line EM is asignal line for controlling the light-emitting control transistor T4 andthe conducting control transistor T5 in one repeating unit group. Thescanning line GA is a signal line for controlling the data write-intransistor T2 and the threshold compensation transistor T3 in onerepeating unit group.

Exemplarily, as shown in FIG. 1, FIG. 3 and FIG. 4E, the overlappedregion is formed between the orthographic projection of the reset lineson the base substrate 10 and the orthographic projection of the anodesin the red sub pixels on the base substrate 10, the overlapped region isformed between the orthographic projection of the light-emitting controllines on the base substrate 10 and the orthographic projection of theanodes in the green sub pixels on the base substrate 10, and theorthographic projection of the scanning lines on the base substrate 10does not overlap with the orthographic projection of all the anodes onthe base substrate 10.

Exemplarily, as shown in FIG. 3 and FIG. 4E, in the same repeating unit,overlapped regions are formed between an orthographic projection of theanodes in the third-color sub pixels spx3 on the base substrate 10 andan orthographic projection of the reset lines for controlling the pixelcircuits in the third-color sub pixels spx3 on the base substrate 10 aswell as between the orthographic projection of the anodes in thethird-color sub pixels spx3 on the base substrate 10 and an orthographicprojection of the light-emitting control lines for controlling the pixelcircuits in the third-color sub pixels spx3 on the base substrate 10.For example, the first-color sub pixels spx1 are the red sub pixels, thesecond-color sub pixels spx2 are the green sub pixels, the third-colorsub pixels spx3 are the blue sub pixels, and in the same repeating unit,the overlapped regions are formed between the orthographic projection ofthe anode in the blue sub pixel on the base substrate 10 and theorthographic projection of the reset line on the base substrate 10 aswell as between the orthographic projection of the anode in the blue subpixel on the base substrate 10 and the orthographic projection of thelight-emitting control line on the base substrate 10 respectively.

A second overlapped region is formed between theorthographic projection of the first via holes GK1 in the green subpixels on the base substrate 10 and the orthographic projection of thesecond via holes GK2 in the green sub pixels on the base substrate 10. Athird overlapped region is formed between the orthographic projection ofthe first via holes GK1 in the blue sub pixels on the base substrate 10and the orthographic projection of the second via holes GK2 in the bluesub pixels on the base substrate 10. An area of the first overlappedregion is not greater than an area of the second overlapped region. Thearea of the first overlapped region is not greater than an area of thethird overlapped region. Further, the area of the third overlappedregion may be roughly equal to the area of the second overlapped region.It should be noted that in the practical technique, due to limitation ofthe technique conditions or other factors such as wiring or forming ofthe via holes, an above equal relationship only needs to roughly meetthe above condition, which all fall within the protection scope of thepresent disclosure.

Exemplarily, the area of the first overlapped region is 0-0.9 μm. Forexample, the area of the first overlapped region may also be 0.5 μm, orthe area of the first overlapped region may also be 0.9 μm, or the areaof the first overlapped region may also be 0 μm. In this way, theorthographic projection of the first via holes GK1 in the red sub pixelson the base substrate 10 may not overlap with the orthographicprojection of the second via holes GK2 in the red sub pixels on the basesubstrate 10.

Exemplarily, the area of the second overlapped region is 0-0.9 μm. Forexample, the area of the second overlapped region may also be 0.5 μm, orthe area of the second overlapped region may also be 0.9 μm, or the areaof the second overlapped region may also be 0 μm. In this way, theorthographic projection of the first via holes GK1 in the green subpixels on the base substrate 10 may not overlap with the orthographicprojection of the second via holes GK2 in the green sub pixels on thebase substrate 10.

Exemplarily, the area of the third overlapped region is 0-0.9 μm. Forexample, the area of the third overlapped region may also be 0.5 μm, orthe area of the third overlapped region may also be 0.9 μm, or the areaof the third overlapped region may also be 0 μm. In this way, theorthographic projection of the first via holes GK1 in the blue subpixels on the base substrate 10 may not overlap with the orthographicprojection of the second via holes GK2 in the blue sub pixels on thebase substrate 10.

Exemplarily, when the first-color sub pixels spx1 are the red subpixels, the second-color sub pixels spx2 are the green sub pixels, thethird-color sub pixels spx3 are the blue sub pixels, the secondoverlapped region may be arranged to be greater so as to ensure adistance between the anodes in the blue sub pixels and the anodes in thegreen sub pixels to avoid color mixing.

Exemplarily, as shown in FIG. 3 and FIG. 4E, the first via holes GK1 inthe repeating units adjacent in the second direction F2 are roughly andsequentially arranged in the second direction F2. For example, the firstvia holes GK1 in the repeating unit groups are roughly and sequentiallyarranged in the second direction F2. Exemplarily, the orthographicprojections of the first via holes GK1 in the repeating units adjacentin the second direction F2 in the first direction F1 are overlapped. Forexample, the orthographic projections of the first via holes GK1 in therepeating unit groups in the first direction F1 are overlapped. Itshould be noted that in the practical technique, due to limitation ofthe technique conditions or other factors such as wiring or forming ofthe via holes, an arrangement relationship of the first via holes GK1only needs to roughly meet the above condition, which all fall withinthe protection scope of the present disclosure.

Exemplarily, as shown in FIG. 3, FIG. 4E and FIG. 4F, the pixel defininglayer is formed on one side of the first electrode layer facing awayfrom the base substrate 10. The pixel defining layer includes openingslocated in all the sub pixels, and in the same sub pixel, anorthographic projection of the opening on the base substrate 10 islocated in the orthographic projection of the anode on the basesubstrate 10. For example, the first-color sub pixels spx1 are the redsub pixels, the second-color sub pixels spx2 are the green sub pixels,the third-color sub pixels spx3 are the blue sub pixels, the red subpixels have openings KK1, the green sub pixels have openings KK2, andthe blue sub pixels have openings KK3. It should be noted that a regionwhere the openings in all the sub pixels are located is equivalent to alight emitting region of the sub pixels.

Exemplarily, as shown in FIG. 3, FIG. 4E and FIG. 4F, in at least onesub pixel in the first-color sub pixels spx1 and the second-color subpixels spx2, the orthographic projection of the opening on the basesubstrate 10 is rectangular. For example, both the orthographicprojection of the openings in the first-color sub pixels spx1 on thebase substrate 10 and the orthographic projection of the openings in thesecond-color sub pixels spx2 on the base substrate 10 are rectangular.For example, the first-color sub pixels spx1 are the red sub pixels, thesecond-color sub pixels spx2 are the green sub pixels, the third-colorsub pixels spx3 are the blue sub pixels, and both the orthographicprojection of the openings KK1 in the red sub pixels on the basesubstrate 10 and the orthographic projection of the openings KK2 in thegreen sub pixels on the base substrate 10 are rectangular.

Exemplarily, as shown in FIG. 3, FIG. 4E and FIG. 4F, an area of theopenings in the third-color sub pixels spx3 is greater than an area ofthe openings in the second-color sub pixels spx2, and the area of theopenings in the second-color sub pixels spx2 is greater than an area ofthe openings in the first-color sub pixels spx1. For example, thefirst-color sub pixels spx1 are the red sub pixels, the second-color subpixels spx2 are the green sub pixels, the third-color sub pixels spx3are the blue sub pixels, an area of the openings KK3 in the blue subpixels is greater than an area of the openings KK2 in the green subpixels, and the area of the openings KK2 in the green sub pixels isgreater than an area of the openings KK1 in the red sub pixels. In thepractical application, the areas of the openings in all the sub pixelsmay be inversely proportional to a light-emitting lifetime of the subpixels. For example, the light-emitting lifetime of the red sub pixelsis greater than the light-emitting lifetime of the green sub pixels andthe light-emitting lifetime of the blue sub pixels, thus the area of theopenings in the blue sub pixels may be greater than the area of theopenings in the green sub pixels, and the area of the openings in thegreen sub pixels may be greater than the area of the openings in the redsub pixels.

Exemplarily, as shown in FIG. 3, FIG. 4E and FIG. 4F, in the third-colorsub pixels spx3, an opening recess AX0 is formed on one side of theorthographic projection of the openings on the base substrate 10 facingthe orthographic projection of the first via holes GK1 in thethird-color sub pixels spx3 on the base substrate 10. For example, thefirst-color sub pixels spx1 are the red sub pixels, the second-color subpixels spx2 are the green sub pixels, the third-color sub pixels spx3are the blue sub pixels, and in the blue sub pixels, the opening recessAX0 is formed on one side of the orthographic projection of the openingsKK3 on the base substrate 10 facing the orthographic projection of thefirst via holes GK1 on the base substrate 10. By arranging the openingrecess AX0, a required area can be fanned out for the first via holesGK1, so as to ensure that anode flatness in the openings KK3 is high,and improve a display effect.

Exemplarily, as shown in FIG. 3, FIG. 4E and FIG. 4F, in the third-colorsub pixels spx3, an orthographic projection of the opening recess AX0 inthe first direction F1 covers the orthographic projection of the firstvia holes GK1 in the first direction F1. For example, the first-colorsub pixels spx1 are the red sub pixels, the second-color sub pixels spx2are the green sub pixels, the third-color sub pixels spx3 are the bluesub pixels, and in the blue sub pixels, the orthographic projection ofthe opening recess AX0 in the first direction F1 covers the orthographicprojection of the first via holes GK1 in the first direction F1.

For example, the first-color sub pixels spx1 are the redsub pixels, the second-color sub pixels spx2 are the green sub pixels,the third-color sub pixels spx3 are the blue sub pixels, and in the bluesub pixels, the edge of the orthographic projection of the openingrecess AX0 on the base substrate 10 is roughly parallel to the edge ofthe orthographic projection of the first via holes GK1 on the basesubstrate 10. It should be noted that in the practical technique, due tolimitation of the technique conditions or other factors such as wiringor forming of the via holes, the above parallel relationship only needsto roughly meet the above condition, which all fall within theprotection scope of the present disclosure.

Further, the third distanceis 2.25-20 μm. For example, the first-color sub pixels spx1 are the redsub pixels, the second-color sub pixels spx2 are the green sub pixels,the third-color sub pixels spx3 are the blue sub pixels, and in the bluesub pixels, the third distance between the edge of the orthographicprojection of the opening recess AX0 on the base substrate 10 and theedge of the orthographic projection of the first via holes GK1 on thebase substrate 10 is not less than 2.25 μm. Exemplarily, the thirddistance may be set to be 2.25 μm. Alternatively the third distance mayalso be set to be 2.5 μm. Alternatively the third distance may also beset to be 20 μm. In the practical application, the third distance may beset to be 2.5 μm when the display panel is produced in batches incombination with the preparation technique and the device precision.Certainly, in the practical application, a numeric value of the thirddistance can be set according to the demands of the practicalapplication, which is not limited here.
